What is the most vulgar word one could use when describing "LIFE" and a phrase for an "ALL-HATING GOD"

Question

I am writing a play and have reached the conclusion where the main character utters a soliloquy of just how "despicably stupid" the concept of "living" and reaching the heights of "happiness" is. Everything has lead up to this most severe moment and thus I am in need of some personal insight. I would like to ask of a word which profanely describes an "all-hating God" who gloats upon the face of his creation's misery and woe.

So I am asking two questions:

firstly, what is a word or phrase (kenning) to describe an "All-Hating God" rather than the more illustriously thought of "all-hallow God."

And secondly, a word to describe "Life" most vulgarly (context: life is damned due to its, in the play's context, "futile nature") and in an almost taboo sense. A word which would instantly put an audience at unease (along with of course the way the actor would say the line) when it is used in the connotation of a concept so "sacred" as "Life." (think of Macbeth's "Out, out brief candle" effect). Of course, I don't expect a single word could so immensely affect a large-scale basis, but I am just in need of some overall opinions.

There is one catch thought, the word(s) must be confined to the vocabulary of the 17th century, more specifically, London 1660s, and I am being extremely uptight on the play's language-timed-authenticity." For this, I have been mainly using the wonderful and virtuous help of "etymonline.com"

Answer 1

In the 1660s any negative description of God would have been likely to have caused public outrage.
